Alright, now i'm getting somewhere. I finally compiled the program without the makefile on code::blocks. The program runs fine, but I have some new questions that I hope others can answer.
A: Why is my compile so slow? I checked all the optimizations I could find in the GNU GCC compiler settings. The downloaded source comes with an executable that runs much faster. Same program but different speeds.
B: The downloaded executable displays information on the "Arena GUI" (i.e. knodes/second, total nodes evaluated) that my executable does not. Why?
C: Are all the free compilers that much slower than the commercial compilers? Is so, that is a major bummer. I'll have to buy me an expensive compiler then.
